The floodgates have opened for developers and enthusiasts to enroll in Apple's Developer Beta program and start testing the newly announced software platforms for feedback. By the looks of it, it's a whopping 20GB update on the iPhone that gets you earlier access to new features like the Liquid Glass slider, Spatial Reframe, and Siri AI (when you pass the waitlist).

Also: Every iPhone model that supports the iOS 27 update (and which older ones don't)

We've got guides up for how to update your eligible iPhone, Mac, or iPad to the latest developer betas, but as always, proceed with caution, as these early-stage software programs can include frequent bugs and glitches -- in the worst case, wiping your device's data.

Following the WWDC keynote, Apple held a private technical deep dive with members of the media, where the company executives, including Craig Federighi and Mike Rockwell, shared some specifics on how the new Siri AI works and why it doesn't experience the same security and privacy vulnerabilities as cloud-based services like Gemini.

Notably, in response to a question about Apple's stance on agentic AI, Federighi suggested that the autonomous workflow remains an "exciting experiment," and that while Apple has the agentic architecture in place with Siri, it's still early days for "long-horizon agentic tasks."

Apple's core philosophy for Apple Intelligence continues to rely on deterministic, highly structured app protocols. Essentially, developers have to explicitly build "app intents" so Siri can safely execute a command, so it's reasonable for the company to hold back on diving into agentic AI capabilities at the start.

And that's a wrap. Tim Cook concludes his last WWDC with a final, fleeting farewell. He says "the best is still ahead" for the company, as he prepares to pass the baton to future Apple CEO John Ternus in September. Cook's work advancing Apple's mission of creating some of the world's best products has been, in his words, "the honor of a lifetime."

In addition to confirming rumors about new Enhance and Extend photo features, Apple announced a new editing tool called Spatial Reframing. It uses a combination of on-device spatial models and facial recognition to optimize a photo of, for example, your family members, giving it a different angle or perspective than the photo you actually took -if it works. We'll have to test it.

I'm a big Shortcuts user, but it's one of those apps that has a steep learning curve. A new update makes it easier for people to use, regardless of their level of Shortcuts experience. Now, iPhone users can simply describe the Shortcut they'd like to create, instead of configuring every setting in the app themselves. 

Originally, users would plug in "do," "if," and "when" prompts to initiate a Shortcut. Now, they can type in their desired Shortcut, such as "When I leave the office, Message John that I'm on my way home, and include my ETA."

Your emails and notes are about to get way more grammatically correct. Automatic proofreading is coming to more apps, including Slack and Mail, and it's powered by Apple's next-generation Siri. This grammar tool will be available in hundreds of apps.

In Safari, Apple Intelligence will now help manage your chaotic and quickly multiplying tabs by organizing them into topics in real time. Safari will now "automatically monitor a page on your behalf" with Notify Me, but doesn't share that browsing data anywhere, said Beth Dakin, software engineering manager.

Apple's Camera app is getting smarter. Users can now activate the shutter button to let Siri AI, powered by Visual Intelligence, see what you're seeing, ask it questions, and respond with helpful answers. Use the camera to learn about the nutrition information in your lunch or split the bill evenly among friends, VP of software Sebastian Marineau explained.

With new features like automatic proofreading in messages and mail and event detail detection in Calendar, Siri AI and Apple Intelligence are doing what users have come to expect from third-party AI tools like ChatGPT and Claude, as well as built-in assistants like Gemini that act natively in the apps they use every day. 

Apple's main distinguishing factor here, as always, is privacy -- the data from whatever you use Apple's AI for won't be shared, even with the company. If the features work competitively, that factor could be enough to persuade privacy-conscious users to leave other assistants behind.

Mike Rockwell, VP of Siri engineering, said "we've rebuilt Siri with powerful AI at the core," introducing Siri AI, a blend of Siri and Apple Intelligence.

Users can access the new Siri by saying "Hey Siri" as always, but now it will be a "profoundly more capable assistant" you can converse with, including via a new dedicated Siri app. It's in Spotlight on MacOS, and Visual Intelligence is here too. 

In a demo, Rockwell showed Siri drawing on current public information to answer a question about a local concert, with the answer displayed on Rockwell's home screen. With on-screen awareness and using personal context, Siri can identify a location from a photo you've pulled up and answer follow-up questions related to the location, including directions, for which Siri opens Apple Maps to display. 

For the last demo, Rockwell told Siri to share only select photos featuring certain people in a family group chat. Another demo showed Siri handling more than one-off tasks, going from request to request to plan a watch party the way you'd use ChatGPT or Gemini, echoing some of the capabilities Google showed Gemini Spark handling at I/O last month. 

These demos showed the revamped assistant doing "the things you'd expect Siri to do," as Rockwell put it.

Before it introduced its new Siri AI, Apple emphasized privacy as a core tenet of its AI approach. This seems to be how it will differentiate its AI offerings from competitors in an already flooded AI space.

New Screen Time limitations allow parents to restrict access to certain apps on their kids' phones. Time Allowances enable parents to set screen time limitations during the day, so their kids can stay focused at school or stop scrolling late at night. The features can be adjusted based on age and development. The screen time restriction feature is one way Apple plans to give more control back to parents and curb unsafe phone use among kids.

To help incentivize boundaries around tech use by younger users, Apple made several child-specific updates to its trust and safety features. 

Raja Bose introduced new Child Accounts, which let parents sandbox their kids' use of Apple products and services using age-based restrictions, including in the App Store. These settings let parents set limits around what kids can see, with whom they can interact, and how much time they can spend on their devices. 

Starting this year, the new settings give kids access to certain essential apps determined by a parent and expand them over time as the child grows older. As Ann Thai explained, kids can request to download apps with their parents' permission, while a similar Ask to Download feature routes them through parental controls before accessing a new site. Ask to Browse and Ask to Buy are on by default for kids under 13. 

Communication Safety, another new feature, censors photos that may contain nudity or violence when detected in messages.

Apple Maps is getting a visual upgrade. Apple announced that it's sharpening the graphics in its navigation platform, so users can get aerial views with finer detail. Visual Intelligence powers the Apple Maps upgrade. Expect to see fuller trees, light reflected off of skyscrapers, and an enhanced view of city streets the next time you pop into Apple Maps.

One year after Apple introduced Liquid Glass, the transparent design interface is getting a welcome upgrade. You can now adjust Liquid Glass through a handy slider in Settings for more or less transparency, Shubham Kedia, Apple's human interface designer, announced at WWDC. This will make the design interface as clear or tinted as you prefer, and create more depth and separation between apps, tabs, and backgrounds.

Apple is bringing more of its features to Android devices. One of the first announced today is the inclusion of Android users in Apple's Shared Albums. This further illustrates Apple's new era of collaboration across iOS and Android devices.

Only a few weeks ago, at Google's own developer conference, did we see the company demo several features on... iPhones? This came as a big surprise. Historically, Apple and Google have stayed in their own lanes, creating products exclusively for iOS or Android users, respectively. 

That subtle flash of an iPhone during I/O symbolizes the start of a new, collaborative era between two tech rivals. Apple needs Google's Gemini to revamp its fledgling Siri, and Google gets to take advantage of Apple's compromised AI position and introduce Android features to devout iOS users.
